a Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS) data are from Heimberg et al. (1992). SIAS-S data are from Rodebaugh et al. (2011). Brief Fear of Negative Evaluation Scale (BFNE and BFNE-S) data are from Weeks et al. (2005). LSAS-CA data are from Heimberg et al. (1999). LSAS-SR data are from Fresco et al. (2001). SAFE data are from Cuming et al. (2009). However, note that Rapee et al. (2009) and Goldin et al. (2016) reported means between 82 and 88 for clients with social anxiety disorder assigned to different conditions in their randomized clinical trials.

b SIAS and SPS data are from Heimberg et al. (1992). SIAS-S data are from Rodebaugh et al. (2011). BFNE and BFNE-S data are from Weeks et al. (2005); LSAS-CA data are from Heimberg et al. (1999). LSAS-SR data are from Fresco et al. (2001). SAFE data are from Cuming et al. (2009).

c SIAS and SPS data are from Heimberg et al. (1992). LSAS-CA data are from Mennin et al. (2002). LSAS-SR data are from Rytwinski et al. (2009).

d The generalized subtype of social anxiety disorder is not recognized in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5; American Psychiatric Association, 2013), but was used to indicate that the client feared all or most social situations in the DSM’s fourth edition (DSM-IV; American Psychiatric Association, 1994) and earlier editions. These data are retained in the current table because they indicate a more severe presentation of social anxiety disorder. SIAS data are from Mennin, Fresco, and Heimberg (1998). LSAS-CA data are from Mennin et al. (2002). LSAS-SR data are from Rytwinski et al. (2009).
